[RFC 03/12] arm_mpam: resctrl: Define new schemata format for priority partition

[Amit Singh Tomar]

At the moment, "schemata" file contains information about cache portion
bitmap (CPBM), and memory bandwidth allocation (MBA) in the following
format.

MB:0=0100
L3:0=ffff

Lets' update the "schemata" file to accommodate information about
priority partition control that indicates downstream priority value.

For instance:

L3:0=ffff,f

CPBM is separated from downstream priority value using delimiter ",".
